‘STROKE’ October 2010. Dr Amer Jafar. Ethnicity and recurrence of stroke. Population-based study Compared poststroke recurrence and survival in Mexican Americans (MAs) and non-Hispanic whites (NHWs) with atrial fibrillation
Comparedpoststroke recurrence and survival in Mexican Americans (MAs)and non-Hispanic whites (NHWs) with atrial fibrillation
Recurrent strokeand all-cause mortality were compared by ethnicity with survivalanalysis methods.
MAs with atrial fibrillation have a higherstroke recurrence risk and more severe recurrences than do NHWsbut no difference in all-cause mortality
Aggressive strokeprevention measures focused on MAs are warranted
The aimof this study was to determine if von Willebrand factor levelsare associated with the risk of stroke
The study was part of the Rotterdam Study, a largepopulation-based cohort study among subjects aged 55 years
During an average follow-up time of 5.0 years,290 first-ever strokes occurred, of which 197 were classifiedas ischaemic
The association was also present in subjectswithout atrial fibrillation and did not differ between sexes
The study concluded that: High von Willebrand factor levels are associatedwith stroke risk in the general population
Aiming to assess how frequentlyMRI/DWI was performed for TIA patients and ascertained the proportionof clinically defined TIA patients who had ischaemic lesionson DWI
All clinically defined TIA cases among residentsof a 5-county region around Cincinnati who presented to emergencydepartments were identified during 2005
Of 834 TIA events in 799 patients, 323 events(40%) had MRI/DWI performed
Patients with positive DWI were older and more likely to have atrial fibrillation
Performing MRI/DWI on all clinically definedTIA patients in the community would reveal more cases of actualinfarction but would more than double current use
The researchers studied the feasibility and safetyof hypothermia (neuroprotection) and thrombolysis after acute ischaemic stroke
Intravenous Thrombolysis Plus Hypothermia forAcute Treatment of Ischaemic Stroke (ICTuS-L) was a randomized,multicenter trial of hypothermia and intravenous tissue plasminogenactivator in patients treated within 6 hours after ischaemicstroke
This study demonstrates the feasibility andpreliminary safety of combining endovascular hypothermia afterstroke with intravenous thrombolysis
Pneumonia was more frequentafter hypothermia
A definitive efficacy trial is necessary to evaluate the efficacyof therapeutic hypothermia for acute stroke.
The research evaluated recent nationwide trends in discharge statintreatment after intracerebral haemorrhage hospitalization
The study used data from 25 673 patients with haemorrhagicstroke admitted to Get With Guidelines–Stroke participatinghospitals between January 1, 2005, and December 31, 2007
Discharge statin prescription among hospitalizedpatients with intracerebral haemorrhage has modestly risen overtime
The clinical implications of this care pattern among patientswith intracerebral haemorrhage require further study
Comparing Early and Delayed Constraint-Induced Movement Therapy
the purpose of this study was tocompare functional improvements between stroke participantsrandomized to receive CIMT within 3 to 9 months(early group) to participants randomized on recruitment to receivethe identical intervention 15 to 21 months after stroke (delayedgroup).
The earlierCIMT group showed greater improvement than the delayed CIMTgroup
Early and delayed group comparison of scores 24 months after enrolment showed no statistically significantdifferences between groups
CIMT can be delivered to eligible patients3 to 9 months or 15 to 21 months after stroke. Both patientgroups achieved approximately the same level of significantarm motor function 24 months after enrolment
The Nationwide Inpatient Sample 2002 to 2007 wassearched for all emergency room admissions for stroke in University of Florida
There were 599 087 emergency room admissions forischaemic stroke: 159 906 weekend admissions and 439 181 weekdayadmissions
The study concluded that: There is a slight stroke weekend effect onthrombolytic use, total hospital charges, and length of stay,but no difference in in-hospital mortality or discharge disposition.
The authors investigated whetherthe presence of a carotid bruit is associated with increasedrisk for transient ischaemic attack, stroke, or death by stroke(stroke death)
The study included 28 prospective cohort articles thatfollowed a total of 17 913 patients
Conclusion: The presence of a carotid bruit may increasethe risk of cerebrovascular disease.
